Sachiko Tanaka

A traunt student of Junichirous who doesnt go to school so she can work as a mangaka under the penname Kisaki Tenjouin. Shes rather apathetic and laidback and seems to only really care about her fans. However she does care about her other classmates at times although her and the student council president Makina Momozono dont seem to be on very good terms. Junichirou calls her Kisakisensei and is a fan of her manga Shuumatsu Gakuen even calling it a masterpiece. Her previous manga was called Hanauta and was supposably very popular until the magazine ceased publication. As such the last chapter was never published.
